Motor problem of vehicle-mounted air pump

Most of the on-board electrical equipment is DC. If alternating current is used, it must be converted into alternating current by inverter, which not only increases the cost but also has low reliability.

The control voltage can reach the control speed, but if the voltage is too low, the motor will block and burn out easily.

Air pressure should be controlled by pressure regulating valve or pneumatic switch. The motor speed intelligently controls the air intake, but it cannot control the air pressure.
